    Oxygen-dependent formation of VO2 thin films by metalorganic aerosol deposition [Articol]
    (Universitatea Tehnică din Moldova, 2018-05-24) Belenchuk, Alexandr; Shapoval, Oleg M.; Zasavitsky, E.; Vatavu, Sergiu; Kiritsa, Arcady; Moshnyaga, V.
    We report on the growth and properties of vanadium dioxide (VO2) on amorphous and oriented substrates by the low-cost and industry-oriented method of metalorganic aerosol deposition (MAD). X-ray diffraction and temperature- dependent Raman spectroscopy confirm formation of single phase tin films. Abrupt change of resistance by 5×103 times and steep drop of infrared transmission from 49 to 10% at 1700 nm pave the way for application of MAD technique in fabrication of VO2-based optoelectronic and thermochromic devices, such as “smart windows”.

    The structure polymer/as-se-s doped by bi for X-ray imaging [Articol]
    (2023) Kiritsa, Arcady; Huștuc, Alexandru; Nasedchina, Nadejda; Vatavu, Sergiu
    The polymer/67at %(As 2S 3) 0,985 (Bi2Se3) 0,015:33 at.% As 2Se3 structure for X-ray imaging has been investigated. The possibility of registering relief-phase images for radiation of “white” spectrum of tungsten anode X-ray tube was shown.

    Сhalcogenide glassy semiconductors of the system as-se-s doped by te for X-ray imaging [Articol]
    (2022) Kiritsa, Arcady; Spoială, Dorin; Vatavu, Sergiu
    The polymer/ As-Se-S-Te structure for X-ray imaging has been investigated. The possibility of registering relief-phase images for radiation of “white” spectrum and λ=0,154 nm of Cu anode X-ray tube was shown.
